Serena Williams announces pregnancy, clearing up Snapchat confusion

The tennis star is in the latter stages of her pregnancy and took to Twitter to ask for some advice.

Serena Williams is expecting.

The most dominant women's tennis player of all time posted a photo of herself on Snapchat Wednesday morning with a caption that read simply "20 weeks." Williams deleted the post, but her spokeswomanconfirmed the pregnancy in a statement hours later.

Williams, 35, is expected to deliver her first child in the fall, according to Kelly Bush Novak, Williams' publicist.
